Hi @Mattieb44,
I'll take care of this query for you.
A customer statement lists transactions posted over a given period. The option for your customer to pay through a customer statement is unavailable. What you can do is include your bank account information within the body of the email message. You'll have the option to edit the email message before sending the statement out. Let them know that your bank account information is included in the message of your email.
Once these bulk payments from your customers show up in the Review tab of your online bank, you'll have to match it to the respective transactions. Additional info about this process is found in this article: Categorize and match online bank transactions in QuickBooks Online.
I'll be around in case you need further assistance. Tag me in a comment below, and I'll get back to you as soon as I can.
